Abstract

A high pressure discharge lamp comprising a ceramic discharge tube (11) having an inner space filled with an ionizable light-emitting material and a starting gas, plugging members (14) each at least partially fixed to an inner side of respective one of end portions of the ceramic discharge tube and each having a through-hole provided therein, conductive members (5) inserted into or through the through-holes of the plugging members, respectively, and electrode units provided (7,9) in said inner space, wherein a material of the plugging members is the same as that of the ceramic discharge tube, and each of the plugging members is gas-tightly joined to the corresponding conductive member with a metallizing layer (15).
